Background/Objective: Patients with intracranial hemorrhage (ICH) have a 30-day mortality rate up to 52%, and the risk of mortality is increased in patients with disease-induced coagulopathy such as cirrhosis. The objective of this study was to evaluate whether 4F-PCC administration mitigates hematoma expansion in ICH patients with cirrhosis not currently receiving anticoagulation therapy compared to standard of care therapies. Methods: This was a single-center, retrospective study comparing adult patients with ICH and history of cirrhosis who received 4F-PCC versus standard of care therapies. The primary outcome was rate of ICH expansion within 24 hours after admission. Results: A total of 58 patients were included with 21 who received 4FPCC vs 37 who received standard of care therapies. The 4F-PCC group had a significantly higher number of patients with Child Pugh Class C cirrhosis (85.7% vs. 48.6%, P = 0.006), higher baseline INR (1.7 vs. 1.4, P = 0.001) and more patients with a spontaneous cause of hemorrhage (61.9% vs. 29.7%, P = 0.01). Stable follow-up head CT was achieved in 68.4% of patients who received 4F-PCC versus 72.7% of patients treated with standard of care therapies ( P = 0.11). Patients who received 4F-PCC had a significantly greater change in INR within 24 hours (-0.2 vs. 0, P = 0.02) and higher rate of mortality (61.9% vs. 18.9%, P = 0.001). Baseline INR > 2 and surgical evacuation for ICH were associated with decreased odds of stable follow-up head CT in the multivariate logistic regression model. Conclusions: A single dose of 4F-PCC did not significantly improve the rate of stable head CT at 24 hours in patients with ICH and cirrhosis. Randomized clinical trials with larger patient populations are warranted to fully determine the role of 4F-PCC in this unique population.

Traumatic brain injury (TBI) is a major cause of death and disability worldwide. Many patients who experience severe TBI have persistent disorders of consciousness. Amantadine and modafinil are used for some neurological disorders; however, a comparison of the 2 medications in TBI has not been reported. This study compared the effectiveness of amantadine, modafinil, and standard of care (SOC) on disorders of consciousness after TBI.All adult TBI patients admitted between January 1, 2017, and September 31, 2020 who received amantadine, modafinil, or SOC treatments were screened. Data collection included: demographics, change in Glasgow Coma Scale (GCS), location of hemorrhage, medication duration, intensive care unit and hospital length of stay, adverse drug reactions, and concomitant sedative medications. Patients in the amantadine and modafinil groups were matched 1:2 with patients who received SOC therapies. The primary outcome was change in GCS ≥ 3 from baseline to discharge.A total of 142 patients met inclusion criteria. Medications were initiated a median of 8 days from admission. Patients in the SOC group experienced a greater improvement in GCS and shorter hospital length of stay compared with amantadine. A change in GCS ≥ 3 from medication initiation to hospital discharge occurred in 46.5% of amantadine patients and 53.8% of modafinil patients.In this study, TBI patients did not benefit from amantadine or modafinil compared with SOC therapies, and no differences were found between medication groups. Further studies are warranted to determine whether the addition of amantadine or modafinil in the weeks after TBI provides benefit.

New evidence and increased use of intracranial devices have increased the frequency of intraventricular (IVT) medication administration in the neurologic intensive care unit. Significant benefits and risks are associated with administration of medications directly into the central nervous system. This review summarizes important literature, along with key information for clinicians regarding the administration, dosing, monitoring, and adverse effects related to IVT medication usage. Multiple medications have supporting literature for their use in critically ill patients including amphotericin B, aminoglycosides, colistimethate, daptomycin, quinupristin/dalfopristin, vancomycin, alteplase, and nicardipine. Sterile preparation and delivery, along with different types of devices that support medication administration, are also reviewed. One randomized, placebo-controlled trial of alteplase demonstrated decreased mortality but no change in good functional outcome. Other reports of IVT medication use are mainly limited to case reports and retrospective case series. There is a need for increased research on the topic; however, several practical barriers decrease the likelihood of a large, placebo-controlled, prospective study for most indications. Providers should consider implementing protocols to maximize safety of IVT medication delivery to ensure optimal patient outcomes.
